[Q] T-Mobile LG G2 stuck in fastboot, can't get into recovery

Update: I messed around with fastboot a bit more and managed to brick it entirely. It's stuck in a boot loop now -- it won't even power off -- and there's nothing I can do about it, so I just took it in to get it replaced.
Hey guys, I know this thread is very similar to others that have been posted, but I've already looked through them and haven't found anything that works for me yet.
My phone was already running rooted stock with TWRP for the recovery. I tried flashing CM10.2 but it was for the wrong model (I downloaded D802 but my phone is of course D801. Oops). Upon reboot, the LG splash screen appeared and then immediately went to a black screen saying
Code:
Fastboot mode started
udc_start()
When I attempt to turn the phone off it just reboots to that screen again. I am still able to use fastboot, and have tried wiping the phone and re-flashing TWRP. It doesn't throw any errors but I still can't actually boot into recovery. I can't use fastboot to flash a new ROM onto the phone though, since it doesn't like .zip archives apparently, and I can't find a .img file of a ROM anywhere.
When I try to use flashtool as described here http://forum.xda-developers.com/showthread.php?t=2541087 it says the device is not connected (probably because it's not in download mode?).
Any help would be much appreciated. All I need to do is get into recovery, it shouldn't be this hard.

That's the same error I got a few days ago when I mis-flashed a new recovery (oops. and be careful when you use 'dd', because a typo can nuke your recovery). I'd get that error message if I tried to boot into recovery, but if I just let the phone boot, it would boot fine. It was easy to fix, but that was because I just used Terminal Emulator to re-flash recovery.
Your best bet might be to go back to stock. Try this thread.

similar issue, but not quite

I'm not in a boot loop, as I can power off and it will stay off. But I am stuck at the Fastboot mode started screen (I can't get download mode to come up). When I do try to get into download mode it flashes for a second, but then goes back to the fastboot mode screen.
I'm hoping to find an image that I can use the fastboot flash recovery command with to re-write my recovery partition.
Any suggestions on where to find this image file? Or am I going down the wrong path?
Thanks,
Joseph

Did you get it to work? I am in the same mode.

I'm stuck here as well. Looking for a fix

Did you guys find a fix? I need help with this...

similar thing here with me
any solution
i cant boot at all, not into download mode, nor recovery,

got this too because i was installing a note3 rom to my d800, acciodentally of coarse. i managed to boot to twrp by doing the power and volume down technique. and from twrp i restored my recent backup

To anyone still stuck in this situation (reboot loop, no recovery etc):
- Unplug the phone from the USB cable
- Hold down the power until the phone turns off
- Wait a couple of minutes with the phone off
- Now hold power and volume down buttons
- When LG logo appears - release power and volume down and hold them again
- When you see a white screen with "reset to default instructions" -- do what it says, meaning pressing the power button a couple of times
THAT should work.

All I did was hold power and volume down until the LG logo came on (not when it flashed for just a split 2nd) and then pressed and held power down again and it came to the white screen. Then I pressed power 3 times and got into recovery

Not sure if you've tried this. To power off fully, press and hold the volume down and power buttons. Do not let go of the buttons. The phone should turn off and the LG logo should appear. Continue holding until after the LG logo disappears. The phone should be fully off and won't turn back on at this point. If you don't see the LG logo, just keep the buttons pressed for about 10-15 seconds and you should be fully powered off by then. You should be able to enter download mode from here (press and hold volume up button while plugging in USB from computer). If you are able to enter download mode, then use the LG mobile support tool in my thread and follow the instructions. This should flash the latest stock system to your phone. If that doesn't work, I have a link to an alternate method for flashing the latest stock system on your phone. Hope this helps.

Try to hold all buttons of your phone down for about 10 seconds and then your phone should restart itself.

Force your device to reboot by holding volume down, home button and power button at the same time. Hold the buttons down until the device reboots.
From then you can attempt to flash stock firmware via Odin and then making sure that you have enabled OEM unlock in developer options and that you have the correct TWRP for your device (Check MD5, to make sure it isn't corrupted)

Didn't help!

hold power button + tap volume down,
just hold vol down,
tap power button (does nothing), only long press restarts.

each time reinstalling twrp
any ideas what I'm doing wrong?

To reboot to recovery you need to hold volume UP + power.

well that's strange, as, on my device, from off:
Volume UP + power takes me to download mode... I have done this several times and it asks me to confirm by then pressing down.
AND, from off
Volume DOWN + power takes me to recovery.
and doing a search, via google and xda all agree with me.
.. but thanks
I never said I couldn't get into recovery... I cannot get from odin into recovery without it first rebooting and therefore wiping my flash.
edit: So I tried it anyway, and got back into download mode, which in a way is kinda good news as, my logic, if I can get back into download mode from a reboot then I should be able to get into recovery from a reboot.

Same same but slightly different

I am having the exact same problems and tried exactly the same things. I am just not able to install twrp because of this. ( I read that it overwrites the recovery with the stock one when you are not going straight into recovery mode after installation) I am stuck at the “Samsung Galaxy note 10.1” screen if try to go straight into recovery.
What is strange though is that with my device: VOLDown (towards the power button) + Power button takes me to download mode and the other combination supposedly to the recovery mode.
This is so frustrating. Done this so many times with other devices but this one just does not give up… I just want to get rid of all bloatware and other crap…..

I've given up, for now, tried every combination I could think... I have a sneaky feeling it must be rooted first. It is the only thing I haven't tried doing.

I am now trying to root it first

I am currently doing just that! Using the files from autoroot . chainfire . eu (can not post links yet haha) . I will let you know how it went!
UPDATE:
It worked! I rooted my device first. After that I flashed my recovery via the TWRP app. I also must say that my device is the GT-N8010 (p4notewifixx). I got confused of all the different models. Still I think it will work with your model aswell! Good luck!

Bootloop, no Recovery, no Download

Hello,
sorry that I have to bother you with this.
I had a S6 (G920F) with Maniacx Ressurection Remix Unofficial OREO 6.10 , with Magisk 7.10 and TWRP 3.2.1 running.
Because of a problem with calls, I flashed a .zip that fixed the problem before (it's CallAudioFix.zip in that thread – can't find it right now, but I can look for it later if it's any help). That sent my phone into a bootloop.
My problem is that I can't boot into Recovery or Download mode. Windows (in a VirtualBox) finds a SAMSUNG_Android device per USB, but ODIN can't find it (doesn't show anything under ID:COM). ADB in my terminal finds the phone, but it shows it as unauthorized, so I can't use it, either.
I appreciate any help – thanks in advance!

Thanks for your tip, didn't work for me, sadly. If I press and hold the combination for the recovery, I get back into my bootloop. If I press the combination for download mode, nothing happens until I hold it for too long and trigger the battery disconnect (volume down + power).

I'll rather avoid trying to remove the battery for that.
If I hold all buttons, I can only get the "Samsung S6" screen to flash for a second before it goes off and on again (tried for a minute as you suggested).
I tried holding the combos before the kernel screen, directly at it and holding it for a minute, but it only sends me back to the bootloop. Also, I don't get any text on the kernel screen.
Guess I have to keep trying around for a bit...

Try after that flash appears for second to press combo fast i remember that worked for me at same state of bootloop

connect to computer while doing and it works

You can boot into recovery without having to plug into a computer by holding power + volume up, and then once you get to the "this device is unlocked, press power key to continue" screen, rather than just waiting for that screen to disappear, press the power key and then you should be taken to recovery... at least, that's how I was able to do it

Ah gotcha, that makes sense, I've never been able to get recovery booting via power + volume up, until I randomly tried pressing the power button at the device unlocked screen, and for some reason doing that took me into recovery

Are you powering off your phone first? If so wait a few seconds after then hold down both power + volume up buttons at the same time and hold for 10 seconds. It still works for me doing it this way.

This works like a charm. I was about to give up my phone because of this predicament, I didn't want to have any issues restoring my phone in the future in case. THANKS A BUNCH!

It's kinda strange but it is bootloader issue. I am on BTK3 firmware (latest Android 10 release) and i'm experiencing such misbehave of key-kombo to enter ot recovery mode since September or October FW update. Has jus tried to downgrade bootloader to initial firmaware (ATGM) by flashing BL in odin and now i can enter recovery by only pressing vol-up + bixby. It work always. Cables, headphones... nothing needed. just keys-combo.
Then i tried to update BL to latest Android 10 (BTK3) and again recovery mode doesn't work. Only if N9860 connected to PC by cable and even with that it doesn't work for me 10 out of 10 times.
Can someone text/call Samsung support to report this issue ?
BTW thanks to @Mentalmuso for helping me!

Same things happen to Android 11.
Tried to flash on my N9860 old BL over Android 11 firmware (was installed before that, all files AP, BL, CP, CSC), flash was ok, but system was unable to load. constantly bootloops. but i was able again to enter recovery without cable and etc. Tried to wipe cache and factory reset from default recovery but no luck - bootloop.
I thought that game over and old BL is not compatible with new android 11.
But then i wanted to try do the same but with custom binaries (@Mentalmuso TWRP and kernel) and ta-da - system loaded from the first try. For me it's surprise. Now i have Android 11 latest FW for TGY (CUA3) with initial BL from the box (ATGM) and everything looks like working fine. No error in OS, no random reboots (at least after 30 minutes of test) and recovery can be simply loaded only by key combo, without any cables, headphones and PC.
I'm happy now =)
Strange thing is that after fladhing old BL system did not show error message that vbmeta changed and some error in vbmeta header. It was showed always on Android 10. But i flashed twrp again (it has vbmeta inside .zip) to be safe lol.
